PocKsT-BooK CLASP.

SPECIFICATION forming part of Letters Patent No. 429,246, dated June 3, 1890.

Application filed March 2B, 1890.

To aZZ whom it may concern:

Be it known that. I, CARL GUs'rAv PFING- STEN, of New York city, New York, have invented an Improved Pocket-Book Clasp, of which the following is a specification.

This invention relates to a pocket-book or similar clasp of simple construction and in which the locking mechanism is formed by two spring-wires anda tapering head that engages the wires.

The invention consists in the various features of improvement more fully pointed out in the claim.

In the accompanying drawings, Figure 1 s an inner view of the box e; Fig. 2, an inner View of the plate g; Fig. 3, a vertical longitudinal section of the clasp on lines x, Fig. l, and y y, Fig. 2; Fig. 4, an enlarged end view of bar d, and Fig. 5 a bottom view thereof.

The letter o represents the body of a pocketbook, over which folds the pocket-book iap b, as usual. To the inner face of fiap b there is secured a box c, perforated at c. Within this box there are attached two cross-bars d at opposite sides of perforation c', Fig. l. The cross-bars are notched at their bottom, as at d. These notches receive the ends of two parallel spring-wires e, stretched lengthwise over box c, so as to project partly over opening c. In order to secure the cross-bars d to the box c, said bars are provided with studs d2,

that are inserted into openings in the box and are then upset.

To the pocket-book a there is secured a conical head or stud f in line with the opening c of the box c. The ap b should also be perforated in line with the stud, as at b', and in order to conceal this opening the outer face of iiap b is provided with a concave top plate g.

In closing the pocket-book the conical stud f will enter opening c and p'ress the spring- Wires e apart. As soon as the widest part of stud f has passed the wires the latter will spring together again to close the clasp and lock the pocket-book. In opening the book the stud fwill in the same manner first spread the wires e apart to clear them and then pass out of opening c.

It will be seen that my clasp is very simple in construction and works with perfect regularity.

What I claim is- The combination of perforated box c with notch ed cross-bars d, having studs d2, by which they are secured to the box, spring-wires e, secured to the cross-bars, and a conical stud f, adapted to be engaged by the spring-wires, substantially as specified.

CARL GUSTAV PFINGSTEN.
